Dell TS-H653F xflashed to SH-S223F not bitsetting



Tried bitsetting in imgburn and nero, both seem to work, but burnt DVD+R’s show booktype still DVD+R (checked with discspeed and dvdinfo). Tried several versions of S223F firmware (ST & SB) using original and codeguy patched bins. Is it possible that the Dell version is not capable of bitsetting? Can they actually remove that functionality? Anybody get a crossflashed S223F to bitset correctly? Any info would be appreciated. Thanks.
